| Abstract: |
| The recombinant inbred lines (RILs) constructed by Dingya No.17 and Tianya No.3. Major gene plus polygene mixed inheritance model was explored to perform genetic analysis of eight traits with the RILs. The results indicated that optimal genetic model of plant height, root fresh weight, shoot fresh weight, root dry weight and shoot dry weight was 2MG-Inhibiting,controlled by two inhibiting major genes plus additive polygene mixed inheritance .The optimal genetic model of root length and leaf dry weight was 3MG-CEA, controlled by three independent major genes plus additive polygene mixed inheritance. The optimal genetic model of fresh leaf weight was 4MG-CEA,controlled by four independent major genes. In RILs populations, the major gene heritability of eight traits was at 9.59%～50.96%. |
